including 3D Blu-ray players, 3D broadcasting and the latest generation games
consoles.

Integrated speaker
The built-in speaker offers excellent audio support. Easy to set up without the
need for costly external speakers

Energy saving
Using the specially designed lamp modes, you can reduce the power consumption by
up to 70%. Each mode also has a positive effect on the lamp life, while lowering
the total cost of ownership and reducing maintenance.

Quick resume
This feature allows the projector to be instantly powered on again, if it is
accidentally switched off.

Auto power off
There may be instances when the projector is left running when not in use. To
help save energy if the projector is left running and no source is detected, the
“Auto power off” feature automatically turns off the projector after a set
period of time.

Eco AV mute
Stay in control of your presentation with Eco AV mute. Direct your audience's
attention away from the screen by blanking the image when no longer needed. This
also reduces the power consumption by up to 70%, further prolonging the life of
your lamp.
